A new type of Thermo-Hygro meter ＜Comfort Zone Indicator＞

The recent models of  Thermo-Hygro meters show not only the number of temperature and relative humidity (RH) but zoning like

Temp: Cold - Comfortable - Hot with colors

Cold: Blue
Comfortable: Green
Hot: Red or Orange

This color zoning is largely following the color temperate though green is located between yellow and blue in color temp.

Humidity: Dry - Comfortable - Wet

Zoning by color is difficult as there is no color humidity.  So there are some confusion.

Dry: Blue
Comfortable: Green
Wet: Red or Orange



















(no brand)

This is the same arrangement as the color temp zoning.

Wet: Blue
Comfortable: Green
Dry: Red or Orange

(no brand)

This arrangement seems better. Wet psychologically relates more with blue than red and orange while dry relates more with red and orange than blue. (<-30> placed in a strange direction but easy to read.)

＜Comfort Zone Indicator＞

When the comfort zone is your concern (in or out of comfort zone) you can find ＜Comfort Zone Indicator＞. ＜Comfort Zone Indicator＞ is not yet an established name of products in the market like thermometer you can guess easily what it is. As an indicator the following MINGLE (German brand, made in China) can be called ＜Comfort Zone Indicator＞. The arrow, instead of common hands (shown in the above products) indicates in which zone your are.

A Digital with Analog ＜Comfort Zone Indicator＞. Good design.

TFA barand. 

Also a German Brand. This photo is indicating almost the most comfortable state in digital (20.9 Deg C and RH60%) by my standard in Hing Kong but Analog shows somehow Wet. Correctly speaking this analog indicator ＜COMFORT＞ only shows ＜COMFORT＞zone in humidity. Very good design.
